During engineering and geological works on the research vessel "Akademik Aleksander Karpinsky" PGO "Sevmorgeologiya" in the Pacific Ocean was tested deep-water research unit UGI-4M, designed to carry out measurements in full-scale conditions of mechanical properties of oceanic bottom sediments at a depth of up to 6000 m.
Currently, the industrial development of the ocean is actively developing and one of the main directions of work on the study of its resources is the extraction of minerals. For the extraction of minerals on the shelf a complex of machines and apparatuses has been created, which includes dredgers, underwater bulldozers of "Komatsu" type, robots "Nihon" and "Komatsu", RUM apparatus, "Hitachi" system, various walking rigs developed and tested in the Soviet Union.
The main supplier of sawing stone for the industry of construction materials is the quarries of the Azerbaijan SSR. The basis for choosing the cross feed of the stone cutting machine is the scheme of stone extraction and sawing adopted at the quarries, according to which the stone is cut by stone cutting machines SM-89M into blocks of 188 x 190 x 390 mm in size.
Traction devices with automatic control of the pressure of the drive wheels against the rolling surface are increasingly used in the mining industry. These devices use drive wheels made of steel, but traction devices in which wheels with rubberised bandages are used as drive wheels are of undoubted interest and have not yet been sufficiently investigated ....
